Which method is NOT effective for reducing the risk of exposure to biohazards?

Neglecting equipment maintenance is indeed not an effective method for reducing the risk of exposure to biohazards. Proper maintenance of laboratory equipment is critical for ensuring that it operates safely and effectively, which in turn helps to protect personnel from potential exposure to hazardous biological materials. Well-maintained equipment is less likely to malfunction or leak, thereby reducing the risk of accidents that could lead to exposure.

In contrast, using personal protective equipment (PPE), following proper waste disposal protocols, and implementing training programs for staff all contribute positively to biohazard safety. PPE acts as a barrier between the worker and biohazards, waste disposal protocols ensure that biological materials are disposed of safely, and training programs educate staff on best practices and safety measures. These practices collectively foster a safer working environment, whereas neglecting maintenance puts everyone at increased risk.
